bug#8511: Sort error in makefile

[Harpal Shergill]

Hello,

I have  a makefile which does the following:

   1. grab a .gz file from server using wget -- works fine
   2. extract the data from .gz file to new file based on filter using ZCAT
   -- works fine
   3. sort the data from based on specific field and saves the data into a
   new file -- DOES NOT WORK


   - command looks like this: sort -t: -k2n <inputFile> outputFile
   - this command works perfectly on command line of cygwin BUT fails
   through makefile
   - Error says: Input file specified two times.

I tried to search on this online but couldn't get any info. Can you please
help and show me what's wrong? In make file i have this command enclosed
with "`" character. Any feedback on this would be greatly appreciated.

Thank you.
